Every day, when throwing away packaging, tearing up paper, or discarding food scraps, we participate in a cycle that few people stop to question. Brazil generates more than 80 million tons of urban solid waste per year — a volume that overwhelms landfills, pollutes rivers, and contributes to greenhouse gas emissions. But the good news is that a significant portion of this waste originates at home, which means it can also be reduced at home.
The question isn’t whether you need to become a composting expert or abandon everything you consume. The question is realizing that small daily decisions add up to real impact. Changing a habit here, rethinking a purchase there — these actions, repeated by thousands of people, change entire systems. And the best starting point is precisely the place where you spend the most time: your home.
This article gathers concrete, accessible practices you can apply right now if you want to generate less waste without complicating your life. Let’s start from the beginning.
Why Generating Less Waste at Home Is More Urgent Than It Seems
The problem with household waste goes far beyond the space it takes up in landfills. When organic waste decomposes in landfills without oxygen access, it releases methane — a gas with global warming potential much higher than CO₂ over a 20-year horizon, according to the IPCC. Plastic packaging that ends up in dumps can take centuries to degrade and frequently ends up in water bodies.
In Brazil, according to the most recent Panorama of Solid Waste in Brazil by ABRELPE, less than 4% of generated waste undergoes any form of effective recycling. This means that most of what we discard goes directly to landfills or improper disposal. Reforming this system depends on public policies — but it also depends on us reducing what we put into this system from the source.
The logic is simple: waste that isn’t generated doesn’t need to be collected, transported, processed, or landfilled. Reducing at the source is the most efficient step in the chain.
Understanding What Actually Generates the Most Waste in Your Home
Before changing anything, it’s worth making an honest diagnosis. Most household waste falls into some predictable categories:
- Organic waste (food scraps, peels, coffee grounds): accounts for about half the weight of Brazilian household waste, according to data from IBGE and ABRELPE
- Single-use plastic packaging (bags, containers, films, small bottles)
- Paper and cardboard (including delivery packaging and online shopping)
- Glass and metal (cans, bottles, jars)
- Electronics and batteries (frequently discarded incorrectly)
Knowing where your home’s waste comes from helps you choose where to start. If you order a lot of delivery, focusing on packaging makes sense. If you cook a lot, organics are the priority.
Simple Kitchen Habits That Cut Waste in Half
The kitchen is, without a doubt, the biggest battleground against household waste. And it’s also where changes are most practical.
Shopping planning against food waste
Food waste is one of the biggest sources of avoidable organic waste. The FAO estimates that about one-third of all food produced in the world is lost or wasted along the chain — and a considerable portion happens inside homes.
- Make a list before going to the market — and stick to it
- Check the fridge and pantry before buying to avoid duplicating items
- Plan the week’s menu, even if approximately
- Buy in smaller quantities more frequently if you have easy access to markets
- Store properly — many foods spoil due to improper storage, not over-purchasing
Whole food utilization
Kale stems, zucchini peels, broccoli stalks, pumpkin seeds — much of what goes in the trash is still edible and nutritious. Learning to use the whole food drastically reduces the volume of discarded organics.

How to Reduce Packaging in Daily Life Without Suffering
Single-use plastic packaging is a well-known villain — but eliminating it completely can seem impossible. The good news is that small substitutions already make a visible difference.
Practical substitutions by category
| What you use today | Lower impact alternative |
|---|---|
| Disposable plastic bag | Fabric tote bag or backpack |
| Disposable PET bottle | Reusable bottle (stainless steel or glass) |
| Plastic wrap to cover food | Lid, inverted plate, or beeswax wrap |
| Disposable plastic cups | Personal mug or cup |
| Synthetic sponge | Cellulose or plant fiber sponge |
The most effective strategy isn’t buying twenty “eco-friendly” items at once — that generates packaging waste and unnecessary spending. The best path is to replace items as the old ones run out, prioritizing what you use most frequently.
Bulk shopping and returnable packaging
Bulk stores allow you to buy the exact amount you need, without individual packaging. Cereals, legumes, spices, flours, laundry soap, and even hygiene products are already available in this format in many Brazilian cities. If you don’t have access to a nearby bulk store, local markets and farmers’ markets often offer unpackaged options for fruits, vegetables, and produce.
Home Composting: Organics Back to the Earth
Turning food scraps into fertilizer is one of the most impactful practices a household can adopt — and it’s more accessible than it seems, even in apartments.
Step by step to start a home composter
- Choose the model suitable for your space: worm composters work well in apartments; garden composters are ideal for those with a backyard
- Separate “wet” materials (fruit scraps, vegetables, coffee grounds, peels) from “dry” ones (shredded cardboard, dry leaves, sawdust)
- Alternate layers of wet and dry to maintain balance and avoid bad odors
- Turn the compost regularly to oxygenate it
- Avoid adding meats, dairy, and fats (especially at the beginning, while learning)
- In 2 to 4 months, you’ll have ready-to-use fertilizer for plants or to donate to community gardens
Even those living in apartments without space for a composter can participate in community composting programs, available in several cities through partnerships with city halls, condominiums, and markets.
Rethinking Consumption: The Root of the Problem
No disposal strategy solves what excessive consumption creates. A fundamental part of generating less waste lies in buying with more intention.
Some useful questions before any purchase:
- Do I really need this or am I buying on impulse?
- Is there a more durable version of this product?
- Can I borrow, rent, or buy used?
- What is the expected lifespan of this item?
- How will I dispose of this product when it’s done?
This doesn’t mean giving up comfort or things you like. It means developing the habit of pausing before consuming — a 24-hour pause before completing non-essential purchases is a simple technique that many people use with good results.
Proper disposal is also part of the solution
Reducing waste isn’t just about generating less — it’s about ensuring that what is discarded goes to the right place. Batteries have specific collection points at pharmacies, supermarkets, and electronics stores. Electronics should go to eco-points or manufacturer reverse logistics programs. Expired medications are collected at pharmacies participating in the National Medication Waste Collection and Disposal Program.
Quick and Actionable Tips to Start Today
If you finish reading this article and want to act immediately, here’s a list of what you can do today:
- Put a tote bag in your purse or backpack for your next trip to the market
- Make a list of what’s in the fridge and plan a meal using what’s left over
- Wash and save a glass bottle to use as a reusable container
- Research the nearest battery collection point to your home
- Set aside a bag or box to start separating recyclables at home
- Cancel paper bills and statements if you still receive them by mail
- Turn on the faucet only when necessary when washing dishes — reduces liquid waste and water consumption
Small actions generate small but consistent results. And consistent results, added up over time and multiplied by other households, create changes that matter.
Conclusion: Your Waste Is Smaller Than You Think — and Can Be Even Smaller
Generating less waste at home doesn’t require perfection or sacrifice. It requires attention: attention to what you buy, what you eat, what you discard. Each new habit you incorporate removes a bit of pressure from a waste system that already operates at its limit in much of Brazil.
Start with just one change. Maintain it for a few weeks. Then add another. Over time, what seemed like effort becomes routine — and routine becomes identity.
The planet doesn’t need a few people doing everything perfectly. It needs many people doing what they can, with consistency and without guilt. And you’re already on the right path just by reading this.
